Rotates clockwise. This allows the clamp arm
The 690 rotates with the biasing force of the spring, and the crumb 691 approaches the turn tail bull 501. At this time, the crumb 691 lifts the CD to the turn tail bull 501 side while being in contact with the center of the CD. As a result, the central portion of the CD is sandwiched between the crumb 691 and the turn tail bull 501.

In synchronization with the operation of the clamper 691, the tip of the rotating piece 420 gradually rotates upward, and the movable shaft 422 resists the biasing force of the spring.
Lift one end of. And a horseshoe-shaped presser ring 42
3 rises with a constant small distance from CD.

When the clamp operation is completed, the motor 502 is driven,
The turntable 501 rotates to rotate the CD.

At this time, the stepping motor 504 is also driven at the same time. The power of the stepping motor 504 is transmitted to the rotary shaft 507 via the small pulley 503, the belt 506 and the large pulley 505. When the rotary shaft 507 rotates, the pickup 510 gradually moves to the right while being guided by the guide rail 511 by meshing with the screw portion 508. Then, after the information in the TCO area of the CD is read by the pickup head of the pickup 510, the pickup 510 moves to a predetermined area and the information recorded in that area is read. In this way, the CD
The information such as music recorded in is reproduced.

To finish reading the information, operate the end button of the control device incorporated in the dashboard. By this operation, the driving of the motor 502 is stopped first,
Then, the drive motor 601 is driven to rotate the rotary cam 610 counterclockwise. As a result, the respective parts operate in the reverse order of the above steps and return to the predetermined positions. And cd
After the clamped state is released, the sheet is transferred to the CD storage tray 101 and stored in a predetermined position in the magazine 100.

When the eject button of the control device is pressed, the drive motor 608 is driven in the opposite direction to that when the CD storage tray 101 is stored in the magazine 100.
The reverse rotation of the drive motor 608 is transmitted to the gear portion 606 via the gear group 607 and moves the slide plate 210 to the inner side. Since the other slide plate 220 is connected to the slide plate 210 via the seesaw lever, it moves in the opposite direction, that is, forward.

By the movement of the slide plates 210, 220, the engagement pins 215, 225
Is pushed up by the stairway grooves 212 and 222. When the engagement pins 215, 225 reach the stepped portions 213, 223, the magazine holder 216 is located at the uppermost position.

When the engagement pins 215 and 225 further advance, the rotation plate 250
The engaging shaft 261 fitted into the long hole 255 of the slide plate 22
It is pushed counterclockwise by the taper portion 227 of the protruding piece 226 of 0, and the engagement portion 201 rotates counterclockwise. as a result,
The engaged state of the magazine 100 is released.

When the engaged state is released, the rotating member 240, which is the eject member of the magazine, rotates counterclockwise by the elastic force of the spring 242. At this time, the rotating member 240 performs a constant rotational movement by the load of the damper 247 meshing with the gear portion 246. Then, the magazine 100 is pushed out of the accommodation space 202 of the magazine holder 216 by the magazine engaging portion 256 of the rotating member 240.

Here, in this embodiment, as described above, the magazine 10
A pair of left and right regulating ribs 219, 219 are formed on the inner surface of the upper side of the magazine holder 216, which faces the upper surface of the push-back action end at the time of loading 0, that is, the front end side.

Therefore, when the magazine 100 is loaded into the accommodation space 202 of the magazine holder 216 against the push-back force due to the engagement with the magazine engaging portion 256 of the rotating member 240, which is an eject member, as shown in FIG. As shown, the magazine 100 has restriction ribs 219, 219 whose upper surface on the push-back action end side is the first restriction member.
The upper surface on the side opposite to the push-back action end is in contact with the guide rail 203 and the guide rib 204, which are the second restricting member. At this time, the regulating ribs 2 have a dimensional relationship such that the magazine 100 takes a predetermined posture.
19, the guide rail 203 and the guide rib 204 are formed.

Therefore, regardless of the pushback action point of the magazine 110, that is, the engagement position with the magazine engagement portion 256, and even when the pushback force of the magazine engagement portion 256 is large, the magazine 1
For 00, the vertical loading posture is properly regulated.

In this way, since lifting of the push-back action end side of the magazine 100 is prevented, the magazine 100 is vertically loaded not only when the multiple type CD player is placed horizontally but also when it is placed vertically. The posture can be regulated correctly.

The pair of left and right restricting ribs 219, 219 provided on the magazine holder 216 in the above-described embodiment is the magazine holder 2
One may be provided at the center portion in the width direction of 16, and instead of these, a plurality of hemispherical projections may be provided.

Further, the present invention is not limited to the magazine holder of the multi-type CD player into which the CD storage magazine is inserted as in the above embodiment, but can be applied to magazine holders using other magazines.

[Effects of the Invention] As described above, according to the present invention, when the magazine is loaded in the magazine holder, the push-back action end of the eject member contacts the upper surface of the front end of the magazine. In this state,
The front end side of the magazine is pushed upward by the elastic force of the push-back action end of the eject member, and the rear end side of the magazine is pushed downward by the moment of the upward pushing force. Therefore, these forces can be received by the first restricting member and the second restricting member, so that the magazine can be properly regulated in the vertical loading attitude in spite of the elastic force of the push-back action end of the eject member. , It is prevented from rising.
